-
23. What is the best path through a curve where you can see all the way to the exit?
Show answer
Answer A: Start toward the outside, move toward the inside, then drift back out
Entering wide, cutting toward the inside and running back out straightens the path, which means less lean angle for the same speed and a better view.
-
24. A rider needs to stop quickly while leaned over in a curve. What is the best technique?
Show answer
Answer D: Bring the motorcycle upright where possible, then brake firmly with both brakes
An upright tire has more traction available for braking, so lean angle should be reduced as brake pressure is increased.
-
25. How should tire pressure be checked and set?
Show answer
Answer B: When the tires are cold, set to the pressure specified by the vehicle manufacturer
Driving heats the air and raises the reading, and the sidewall number is a maximum rather than a recommendation, so check cold and use the figure on the vehicle placard or in the owner's manual.
